EYELETlNG-MACHINE.

SPECIFICATION forming part: of Letters Patent No. 368,875, dated August 23, 1887.

' Application filed May 10. 1887. Serial No. 237.717. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. CORMAN, a citizen of the United States, residing at Go chituate, in the county ofMiddlesex and State of Massachusetts, have invented certain new and useful Improvements in Punching and Eyeleting Machines for Boots and Shoes and for other Purposes, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertainsto make and use the same.

My present invention relates to certain improvements in the construction of various parts of the mechanism and to the combination of the devices employed, in the manner hereinafter explained, with a view to the production of a more convenient, desirable, and practically efficient machine for punching and setting eyelets in fabrics, the particular subject-matter claimed being hereinafter definitely specified.

In the drawings, Figure 1 is a side View of a punching and eyeleting machine, illustrating the features of my invention. Fig. 2 is a plan view of the same. Fig. 3 is a plan view showing the details of the bed-lever and feedchanging mechanism. Fig. 4is avertical section of the same at 'line to w in Fig. 3. Fig. 5 is a plan view of the lever for Working the under eyelet-setting tool. Fig. 6 is a vertical sectional view showing the details of the punch, eyelet-sets, and eyelet-delivering mechanism. Fig. 7 is a plan view of the end ofthe eyeletchute and devices for controlling the delivery of eyelets, and Fig. 8 is a transverse section of the lower eyelet-set bar at line :0 a: in Fig. 6.

Referring to parts, A denotes the frame.

B indicates the operating-shaft, disposed in horizontal position to rotate in bearings a a at the rear part of the frame, and having mounted thereon a series of cams for working the several levers that actuate the punching and eyeleting devices, and provided with a pulley, B, for the driving-belt, whereby the machine is to be operated by power transmitted from any convenient source. Pulley B may, in practice, be connected with the shaft B by an au-- part lateral movement to said lever.

lution of the shaft B, and controlled by a treadle mechanism in the usual manner. The automatic stop-clutch mechanism I have not herein shown, as it is well known, and is not essentially a feature of my present invention.

It will be understood that the several cams are grooved or shaped so that they impart the desired quality and quantity of movement to the respective parts operated thereby, and that they are relatively disposed upon the shaft in such manner that they will bring the working devices consecutively into action in their proper order and at the required intervals of time.

0 indicates thelever which carries the punchingtool c. It is fulcrumed by the stud D upon the bed-lever D to move laterally in unison therewith, and is operated by an auxiliary lever, O, that works in conjunction with the cam G on the shaft 13. The auxiliary lever O is fulcrumed on an arm, A, of the frame A, and is coupled with the lever O by a loose sliding joint at 0 forming a compound punching-lever, the cam-bearing roll of which is at c. As the cam-roll is raised, the punch 0' is depressed, and vice versa. This compound lever action permits the side movement of the lever O with the bed-lever D, to' accommo date itself at the connecting-joint c and thus obviate side movement of the part 0, and con;

The bed-lever D, which serves to carry the the main frame A by means of an adjustable stud, I, that passes through a sliding block, D disposed within the slot of the lever. Said bed-lever is operated by the cam D upon the shaft B, the movement of the bearing-roll d in the groove of the cam being such as to im- The adjustment of the stud I is effected by means which will be hereinafter described.

ICO

The anvil or punching-die d is supported in or upon the forward end of the bed-lever D, and projects up through a slot in the worksupporting table A. An ordinary cuttingpuneh may be used for leather-work; but for use on cloth or similar fabric the punch is best made as illustrated in Fig. 6-that is, as a sharp-pointed stiletto, the anvil d being made with an opening, into which the point of the stiletto enters, so as to force it through the fabric. The feeding is effected while the fabric is gripped between the punch c and anvil d by lateral movement of the levers G and D, the ends of which pass to a position that brings said punch and anvil axially in line with and between the upper and lower sets while they are near their extreme points of separation, and the punch and die then separate, leaving the work with the punched hole in position for receiving the eyelet'and sets.

The bed-lever D is provided with guidingslots 0, which engage studs E, fixed on the frame, or with other equivalent guiding devices, whereby the said lever is confined to a line of motion that will bring the anvil and punch into a position coincident with the vertical axis of the eyelet-sets at whatever position its fulcrum I may be adjusted or whatever the sweep or distance which the punch and anvil move when feeding forward the work. The studs E are preferably provided with anti-friction rolls where they pass through the slots 6 in the head of the bed-lever.

F indicates the top set-lever, fulcrumed on the rod or shaft a, and carrying at its forward end the eyelet-setting tool f, of ordinary any suitable construction. Said lever is operated for depressing and raising the settingtoolf by the cam F fixed on the shaft B.

II indicates the lower set-lever, fulcrumed on .the rod or shaft a, and having its forward end connected by a pivoted link, h, and collar h with the vertically-reciprocating bar K, which carries the lower eyelet-setting tool, K. The lever H is operated for raising and depressing the setting-tool K by means ofa link or strap, H, that embraces an eccentric, H fixed on the shaft B. The bar K is formed as shown in detail in Figs. 6 and 8. The eyelet-setting tool K is secured therein by screwthreads at k. The picker-pin J passes through the setting-tool K, and is provided with a confining-head that rests upon a slide-block, J, fitted to move up and down within the hollow of the bar K. The bar K is longitudinally slotted, as atj, and the slide-block is provided with a cross bar or pin, J, that extends out through said slots j suffieiently far to engage with the bearings a A spring, K is disposed within the bar K beneath the slide-block J, for exerting an upward yielding pressure against the picker-pin J. By the use of the slide-block J and its projecting pin J I attain a positive action for forcing the picker J from the setting-tool K in case said picker, when depressed, becomes clogged or wedged by Small chips or other substance, so that the spring cannot raise it. The ends of the pin J strike the top of the bearing a as the bar K descends and prevents the picker from being carried below the given position, thus utilizing the full running force of the machine for' ejecting the picker, if necessary, while in no way interfering with the normal yielding action of the spring as the parts are elevated. The position of the scttingtool K for properly effecting its work in relation to other parts may be accurately adjusted by the screw-threads k.

L indicates the presser-lever, fulcrumed on the rod or shaft a and operated by the cam L on the shaft B, which engages the follower-roll Z on the rear end of the lever, (see dotted lines, Fig. 1,) and lifts the presser-foot L from the work while it is being fed forward by the punching devices. The presser-foot L may be of ordinary form. A rod, L", connects the presser-lever with a suitable treadle, by means of which the presser-foot can be lifted for introducing the fabric beneath it.

M indicates the eyelet-feed lever. This is fulcrumed on the rocker-shaft m at the outside of the frame. Its rear end is provided with a slot, m, that engages with a crank or wrist pin roll, M .on the crank-plate M fixed to the end of the shaft B. Said lever M is provided with an arm or arms, M M", for supporting the eyelet-feeding chute N and supply-hopper N. In the present instance the arm M that supports the chute, is keyed to the rocker-shaft m, said shaft being keyed to work with said lever M; but, if preferred, said arm might be a part of the lever M, with its top end offset to reach the chute. It will be understood that the arm M and lever M swing in unison for carrying the delivery end of the chute over and away from the picker-pin J for delivering eyelets thereto. The slot m in the lever M is curved, so as to give a stop or retardation in the action of the eyelet-feed while the eyelet is passing through to allow ample time for the other parts to perform their work. By the action of the lever M working on the crank M, the eyelet-hopper N is given a pcculiar upward and downward'action, as well as forward and back movement, which throws up the eyelets within the hopper ateach movement of the lever and prevents the eyelets from settling down into a compact solid mass, and thus greatly facilitates the proper feeding of the eyelets down the chute.

The forward end of the chute N is horizontally slitted at a, (see Figs. 6 and 7,) and a laterally-swingingspring-pressed stop hook or finger, N, is provided for retaining the eyelets 1', except as they are taken off by the picker. The end of the finger N is made of a size that will pass into the slit a, and said finger is pivoted or flexibly connected to a backwardly and forwardly movable slide, P, mounted on the arm M or other equivalent support, in connection with the chute, and a suitable spring, 1, is provided for pressing forward the slide P to its forward position. A spring, 11, is provided for normally retaining the finger N in position for stopping the eyelets. The finger N for stopping eyelets may be the same book or finger that prevents the eyelets from falling from the end of the chute, or it may be a separate hook or finger specially adapted for drawing back the eyelets.

The screws 10, which attach the slide 1? to its support, pass throughslots. Said slide is-provided with a lug or projection, P", that is engaged by the bar or stopping device P, which latter is arranged in connection with the frame A and operated by suitable treadle mechan- Y ism. When the chute Nis moved back, if the bar]? is raisedits end obstructs the forward movement of the slide P, so that as the chute advances the finger N is drawn into the slit n, thereby forcing the eyelets r backward in their delivery-groove away from the extremity of the chute, so that while the end of the chute will come into its usual place over the eyeletset K there will be no eyelet at its extreme end in position to be taken off by the pickerpin J. This method of stopping the feed of eyelets in a punching and eyeleting machine, by stopping or forcing back the eyelets in the groove of the delivery-chute and retaining them out of reach of the picker while the chute makes its normal action, is a feature of my invention.

R indicates the lever for lifting the stop suitable treadle, (Not shown.) Aspring, R,

acting between the bearing and a collar on the bar P serves for depressing said bar and for returning and retaining the parts connected with the lever It at their normal positions.

R indicates an upwardly-extended arm on the treadle-actuated lever B. Its upper end is connected by means of a universally-jointed link, It, with a lever, I, through which the fulcrum pin or stud I of the bed-lever is passed. Said lever l is fulcrumed on a suitable bracket, or part of the frame A, as at t, and extends laterally and substantially horizontally across the'machine, its free end being in the present instance provided with a handle, I". The pivot-stud I passes through the bearingblock D which slides in the slot 02, formed in the bed-lever D, also through a slot in the shifting-lever I, and through the slot a in the supporting-bracket A, the arrangement being such that when the lever I is swung backward or forward the pivot I will be shifted, thereby changing the fulcrum-point farther from or nearer to the front end of said lever D, to increase or diminish the distance of lateral movement of the anvil and punch, thus varying thefeed or spacing between the holes that are punched in the material operated upon.

The slot a in the supporting-bracket is disposed in such relation to the alignment of the lever D that the variation of action incident to the shifting of the fulcrum-pivot I will be effective at one side only, or so that the punch c and anvil (I will swing accuratelyinto alignment with the axis of the eyelet-sets at whatever position the fulcrum-stud I may be adjusted; hence when feeding forward the work the punches will leave the fabric with the hole formed therein in proper position to receive the eyelet, whether operating by a long or a short feeding movement. Beneath the shifting-lever I there is a segmental index-plate, T, having aseries of holes, 15, in which to insert pins T and T that serve as stops for gaging the movement of the shifting-lever I, one in front and one in rear of said lever. In the operation of this mechanism, when the lever B is depressed, its arm R and link It swing back the shifting-lever against the rear stoppin, 1", increasing the length of feed, and at the same time the feeding of eyelets is cut off by the bar R and slide mechanism P; hence in the eyeleting of shoe-uppers, wherein itis desired to use lacing-studs at the top part of the uppers, the desired variation between eyeletspacing and the stud-spacing can be effected, the eyelets set for such portion as required, and the uneyeleted holes punched for the insertion of the lacing-studs by continuous operation and without taking the work from the machine or stopping to make change of feed, as the operator can, by simply placing his foot on a treadle and depressing the lever B, effect this result while the machineis running. When the treadle-lever R is released, the parts return to normal position. This mechanism for the simultaneous stopping of the eyelets and the change of spacing or feed is a feature of my invention.

When it is desired to set the eyelets at uniform distances apart without changing the feed and without stopping off the. eyelets atany portion of the work, the shifting-lever 1 may be confined at any desired position by placing the pins Tand '1 close against it at either side.

In case it is desired to change the spacing or feed without cutting off the delivery of eyelets at the same time, the set-screw in the collar P may be loosened, so that the stop-bar P will not be worked by the action of the lever 'B when said lever is moved for operating the shifting-lever I.

The stops for the lever 1 may be pins, as T T, or any other device for limiting the movementofthe fulcrum-block. The bed lever acts positively in both directions, and no spring is required.

V indicates a spiral rotator for imparting movementtothe stirrer,brush,orfingerswithin the eyelet-hopper. Said rotator consists of a flat spirally-twisted projection connected to the spindle of the hopper and passing through a slot formed in the stationary bracket V, fixed to the frame. The sides of the slot embrace the sides of the rotator, and as the hopper rises and falls oscillative rotation is imparted to the spindle by the spiral surfaces sliding up and down in the slotted bracket in the manner of a screw.

I am aware that punching and eyeleting mameans for changing the feed or spacing between the holes, and, also, that it is common practice in machines of this class to employ means for stopping the delivery of eyelets; but, so far as I am aware, the mechanism employed for effecting such results is essentially different in construction and operation from that herein shown and described.

I am aware that in a previous patent apunching and cycleting machine has been described wherein facilities are afforded for changing the extent of feed movement and stopping the delivery of eyelets, so that holes for lacing-studs may be formed at different spacing from those for the eyelets. The means for attaining such results are, however, essentially different in construction and method of operation from those herein described.
